Abstract:
We present an update of the scale setting for Nf = 2+1 flavor QCD using gradient flow scales and pseudo-scalar decay constants. We analyze the latest ensembles with 2+1 flavors of non-perturbatively improved Wilson fermions generated by CLS for improved precision. Special care is taken to correct for mistuning by measuring directly the mass derivatives of the various observables. We determine t0 with input taken from a combination of leptonic decay rates of the Pion and the Kaon.

Brief introduction of the dida co-author(s) and relevance for dida's ML developments.
Ben Strassberger (PhD)
During his physics studies in Berlin, Ben specialized in computational theoretical particle physics. In his subsequent doctoral research, he focused on lattice QCD, where he developed and optimized highly parallel numerical solvers for large-scale simulations. After gaining experience in software development
and working on complex energy system modeling, he combined his expertise in high-performance computing with practical software engineering. At dida, he leverages his strong background in theoretical physics and numerical optimization to develop robust, scalable solutions for the machine learning team.
